PLOW.

SPECIFICATION forming part of Letters `Patent No. 420,247, dated January 28, 1890.

Application nea Apiii, 188s.

To all whom it may concern.-

Be it known tha't I, HANS H. SATER, of Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Plows; and I do hereby declare the following to bea full,` clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to plows, and more particularly to metal-beam plows and means for attaching a clevis and a colter to such a plow.

The object of my invention is to provide a simple, durable, and inexpensive means for attaching1 a clevis to an iron-beam plow.

A further object of my invention is to provide an improved device to secure a colter to a plow.

A still further object of my invention is to provide a colter of improved and novel construction.

The invention consists in the combination, with a plow-beam, of a bifurcated bracket secured to the forward end of said beam and provided with suitable bearings to support the clevis.

The invention further consists in the combination, with a plow-beam, of a frame having passages for the beam and colter-stem arranged at right angles.

The invention still further consists in providing a colter of improved and novel construction.

The invention still further consists in the details of construction and combination of parts hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure l represents a perspective view of the forward end of a plow-beam with' my improvements applied thereto. Fig. 2 represents the bracket mounted on the forward end of the beam. Fig. 3 shows a perspective view of the frame detached. Fig. 4 is a sectional View of the frame. Fig. 5 shows the clamping devices. Fig. 6 is a plan view of the colter. Fig. 7 is a sectional view taken on line x Fig.'6; and Fig. 8 is a perspective View of the hub detached.l

Referring' to the drawings, A represents a plow-beam. As my invention is intended to Serial No. 270,336. (No model.)

r provide means for attaching clevises and colters to metal-beam plows, I have'so illustrated it; but it will be understood that I do not limit my invention to that use, as it may be used on plows of different construction with equal facility. To the forward end of the beam A a bifurcated bracket A is secured. The bracket A is preferably constructed of metal, and is bifurcated at its rear end, as shown at A2, the bifurcated portion extending some distance through the body of the bracket. The upper portion of the bracket A is provided with laterally-eX tending flanges a a. The upper faces of said iianges are flush with the upper side of the bracket, and thus form a bearing for the clevis. The said bracket and beam are provided with suitable bolt-holes, through which pass bolts a a', which are secured, and thus rigidly secure the bracket to the forward end of said beam.l The bracket A is also provided with vertical bolt-holes a2 and as.

B represents a clevis of ordinary construction provided near its rear end With a perfo ration B and a series of perforations B2. A pin b passes through the perforation B and the bolt-hole a2, thereby forming a pivot-connect-ionbetween'the clevis and the bracket.

The clevis can be adjusted by removing a.

pin b ,which passes throughone of the series of perforat-ions B2 and the bolt-hole a3, turning the clevis until the desired 'adj ustment is attained, and then replacing the pin b.

From the foregoing description it will be seen `that I provide a durable and inexpensive way of adjustably attaching a clevis to a metal-beam plow, thereby overcoming difficulties and inconveniences which have hitlierto been experienced.

C represents a frame mounted on the beam A at a designated point and which is intended to support a colter.

It will be seen on reference to the drawings thatthe frame C is provided with a horizontal passage C and a vertical passage C2. The interior of the frame C being hollow, the passages are connected with each other. On the side of the frame adjacent to the passage C2 a screwthreaded perforation is form ed and a thumb-screw c is placed therein.

D represents a colter-stem constructed withV ICO a vertical portion d, a horizontal bent portion d', anda depending vertical portion d2. VTo enable the frame to be clamped to the beam and at the same time to clamp the stem D, I have constructed a set of gibs E E', Whose adjacent faces are formed to correspond to the contour of the portion cl of the stem D, so that said stem may be clamped therein. The gibs E E are so arranged in the frame that the thumb-screw will press againstV the outer face of the gib E, and that the outer face of the gib E is pressed against the beam. The gib is formed at its upper end with a projecting portion e, which rests on the upper edge of the beam and prevents the gibs from being displaced when the thumb-screw is loosed to permit the adjustment of the col'- ter; hence, it will be seen that when the thumb-screw is tightened it will at the same time make a rigid Vconnection between the beam, frame, and colter-stem.

To the lower end d2 of the colter-stem D are secured,by.suitable means, two supportingarms F F, which pass rearwardly and are at thesametime inclined downwardly. The

said :arms are provided on their ends with journal-boxes, inwhich a colter F revolves. Y VThe colter `F `consistsof a hub G, providedv withanexternalannular flangeG. A colterblade G2 is arranged upon said flange G and secured thereon'by Ya plate g and suitable bolts passing through the'plate, blade,and flange. The lends of the hub G are formed with annular grooves H, as shown in the drawings. 'Anoil-receptacle'I-I is constructed within the hub G and hasan inlet Ak7L. iUponl each side of the hubare internally-threaded, washers J. These washers are'provided on their inner ends `with overlapping flanges'J, which hold the hub G in position,"and they also have annular grooves I on their faces which are adjacent to the grooved faces of the'hub, which correspond with said grooves H. The washersJ are provided witheXtend-i ed portions 7,- whichv form bearings, and they are placed in the journal-boxes on the ends ofthe arms F F. A' bolt K,'sc rewthreadedl' in opposite directions `on its ends; is passed through the washers and hub and `is secured inplace by a 'nut 7c and a lightwasher k.

The washers J are provided Withjhexagonal or equivalent shaped external portions M, so that they may be adjusted with a wrench 0r other suitable tool relative to the hub.

It will be understood that I do not confine the application of my invention, and especially the stem D, supporting-arms F F, and colter F, to metal-beam plows, but reserve the right to make all necessary changes in the construction of said parts, and also in their application to plows, as may properly fall within the scope of the following claims.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a plow-beam, a colter, and an intermediate fastening consisting of a frame C, having a `passage C2 for the; plowbeam, gibs E and' E within said frame, and a set-screw H, whereby the gibs maybe clamped together on a supporting-stem D, and whereby the gib E may be joined against the plowbeam, substantially as set forth.

2. An improved colter consisting of the supporting-arms FF, nutsJ`J, having, grooved faces and mountednear-the end ofeaoh'arm, a flanged hollow hub H, mounted between said nuts, a colter-blade G2, secured to said flanged hub, a screw-threaded rod K, connecting said nuts J .I and passing through said'hollow hub, and nutslc at eachend ofv saidl'rod, substantiallyas set forth. v A

3. The combinatiomwith the beam, colterstem, and frame having passages, ofjgibsE E arranged within said frame, the adjacent faces of the said gibs' constructed to conform to the contour of the colter-steimthe other face of the gib E provided with a'proj'ecting portion e, adapted to rest upon the `beam,and a set-screw attached to gib LE, substantially as described.

In testimony whereof I have signed this specilicationl in' thepresence of two subscribing witnesses.

H.V H. SATER'.
